MSR Base Layer Short and Long Sleeve

Base Layer fabric is 50% lighter than the standard cotton t-shirt. After 60 minutes of exercise the Base Layer fabric releases 80% of its moisture, after 30 minutes of rest, cotton releases only 40% of its moisture.

Made with compression garmets that will hold your muscles in place longer and reduce body fatigue. Less chance for pulled and sore muscle tissue. 2 different layers of fabric: inner layer contains fibers that will wick the moisture off the skin quicker, creating a cooler inner climate.

Once the moisture is separated from you skin the outer layer will evaporate the moisture evenly and fast. Fabric is spun with wicking and anit-bacterial treatments.
